Global cropping
More seriously, the productivity of world agriculture faces a serious decline this century unless emissions of carbon dioxide and other greenhouse gases are substantially reduced.
Developing countries will suffer much steeper declines than high-income countries, according to a study by the Center for Global Development and the Peterson Institute.
Developing countries, many of which have average temperatures that are already near or above crop tolerance levels, are predicted to suffer an average 10 to 25 per cent decline in agricultural productivity by the 2080s, assuming a so-called “business as usual” scenario in which greenhouse gas emissions continue to increase, according to the study. Rich countries, which typically have lower average temperatures, will experience a much milder or even positive average effect, ranging from an 8 per cent increase in productivity to a 6 per cent decline.
